64 Studio is a collection of native free software for digital content creation on x86_64 hardware (AMD's 64-bit CPUs and Intel's EM64T chips). It's based on the pure 64 port of Debian GNU/Linux, but with a specialised package selection and lots of other customisations. The distribution includes the Linux kernel with realtime preemption patches, the GNOME desktop, and a selection of creative applications, covering audio and music, 2D and 3D graphics, and publishing for the Web and print. It also includes Internet and office tools that a creative user is likely to need for their daily work.
AZR3-JACK is a port of the free VST plugin AZR-3. It is a tonewheel organ with drawbars, distortion and rotating speakers. The original was written by Rumpelrausch Täips. The organ has three sections, two polyphonic with 9 drawbars each and one monophonic bass section with 5 drawbars. The two polyphonic sections respond to events on MIDI channel 1 and 2, and an optional keyboard split function makes the bass section listen to the lower keys on channel 1. The three sections have separate sustain and percussion switches as well as separate volume controls, and the two polyphonic sections have separate vibrato settings. All three sections are mixed and sent through the distortion effect and the rotating speakers simulator, where the modulation wheel can be used to switch between fast and slow rotation, and the fast and slow rotation speeds themselves can be changed separately for the lower and upper frequencies.
Allegro Sprite Editor (ASE) is a program specially designed with facilities to create animated sprites that can be used in some video game. It lets you create static images, characters with movement, textures, patterns, backgrounds, logos, color palettes, etc. It focuses on pixel editing to do pixel art. It isn't a photo retouching tool or a vector graphics editor. Mainly, it is a tool to create tiny animations pixel-by-pixel.
Alphabet Soup is a project which attempts to determine a number of things about the shapes of letters in several different writing systems. First, it hypothesizes a set of basic building blocks that all letters are built up from. Second, it hypothesizes a set of rules, a grammar or syntax, which defines how those pieces combine to make different letters. It can generate individual letters, randomize letters in an input string to create weird but readable text, or generate random strings of symbols.
Audiality is a highly scalable and portable audio engine and synthesizer. MIDI files are used in combination with scripting and modular synthesis, to minimize file sizes and maximize flexibility. Audiality can be used as a music and sound effects player in multimedia productions, or as a realtime MIDI synthesizer.
Autocomp is an accompaniment generator for Perl and Csound. It takes as input a text file containing chord changes, plus time signature and bpm information, and outputs a Csound .sco file containing a simple arrangement of those changes. A sample Csound .orc file containing a bass instrument, a selection of keyboard instruments, and a small sample-based drumkit is provided.
The CMU Midi Toolkit (CMT) is a collection of software for writing interactive MIDI software in C. It includes a number of handy utilities along with an application "shell" that provides timing, scheduling, and MIDI interfaces that are portable across DOS, Mac, SGI, and Amiga platforms.
Csound is a powerful and yet easy to use musical synthesis package. Csound was constructed in the tradition of so-called music-N languages, among which the best-known is Music V. It consists of an orchestra- and score-driven executable, written in C for portability. Since Csound is a computational language, it is highly flexible and efficient; complexity is gained only at the expense of computation power. Basically, Csound reads some files and creates the result as a sound file on disk or, on faster machines, in real time through a DAC.
